Sepp Blatter, the suspended FIFA president currently under investigation for financial misconduct, is in hospital after suffering a "small emotional breakdown".
The 79-year-old was admitted to hospital in Switzerland last week for a health check-up due to stress-related issues, but his lawyer Richard Cullen said at the time: "He is fine and expects to be home shortly."
He is set to remain in hospital until next Tuesday after his initial admittance last week.
Blatter resigned from his presidential post in June in the wake of a corruption scandal, but has continued to work for FIFA. The Swiss attorney general announced in September that Blatter would be charged with criminal mismanagement and misappropriation for a "disloyal" payment made to UEFA president Michel Platini.
Blatter, who headed the governing body of world football for 18 years, and Platini were provisionally suspended for 90 days last month by FIFA's ethics committee. Both deny any wrongdoing, and Blatter is said to be appealing the ban.
According to the BBC, Blatter has suffered "a nervous shock" but is expected to make a full recovery.
